Chinese Medicine almost always emphasizes increasing blood flow to the reproductive area when attempting to conceive. The following poses, which aid in conception, are usually added to a gentle and restorative yoga practice. Geeta Iyengar recommended them because of their possible effects on regulating hormonal imbalances.
A very famous teacher, Geeta S. Iyengar, author of Yoga a Gem for Women (Allied, Publishers Limited, 1983), writes extensively on women's issues. She stresses the importance of practicing several asanas to aid in conception. Salamba Sirsasana (Supported Headstand), Salamba Sarvangasana (Supported Shoulderstand) , and Setu Bandha Sarvangasana (Supported Bridge Pose) are recommended because of their hypothesized effects on hormonal balance.
She also recommends the following poses:
Forward Bends: To make the poses more restorative, place a chair in front of you and rest your head and arms on the seat for support, or use a bolster for support.
Dandasana (Staff Pose)
Baddha Konasana (Bound Angle Pose)
Janu Sirsasana (Head-to-Knee Forward Bend)
Paschimottanasana (Seated Forward Bend)
Upavistha Konasana (Wide Angle Pose)
Malasana (Garland Pose)
Reclining Poses: These poses are helpful because they open and elongate the abdominal area.
Bound Supta Baddha Konasana (Reclined Bound Angle Pose)
Supta Virasana (Reclined Hero's Pose)
She also recommends Viparita Karani (Legs-Up-the-Wall Pose) after coitus (which will theoretically keep the sperm inside the body and close to the opening of the uterus) to encourage the opportunity for sperm penetration. Before coitus set up for Viparita Karani (Legs-Up-the-Wall Pose). As you move into and out of the pose, keep the abdominal area soft-your partner can assist you to make this possible. The amount of time you spend in Viparita Karani is up to you.
To set up for Viparita Karani: Fold a sticky mat into quarters and place it two inches from the wall. Place a round bolster or a firm folded blanket on top of the sticky mat with the back edge of the bolster or blanket in line with the back edge of the mat. Place the buttocks on top of the bolster with the sitting bones as close to the wall as possible and the legs up the wall. The tailbone should tilt toward the ceiling so that the vaginal area is pointing upward. The shoulders, arms, and head rest on the floor. Once in the correct pelvic position, allow the legs to soften and bend the knees to allow the abdominal and pelvic floor to relax.
